Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sorting device for sorting brown rice from mixed rice after hulling in a huller.

[Conventional technology]

Generally, a rotary sorting barrel with a number of concave portions formed on its inner circumferential surface is installed horizontally, and at one end of the sorting barrel, the mixed rice that has been culled by a culling device and the rice husks have been sorted by a wind sorter is placed. On the other hand, the rotary sorting device has brown rice receiving troughs with open tops extending in the axial direction of the sorting barrel in the sorting barrel, so that the mixed rice fed into the sorting barrel is sorted. As the mixed rice moves to the discharge side by repeatedly raking it up to the height created by the rotation of the barrel and then falling to the bottom, forming a fluidized bed, the brown rice of the mixed rice is stuck in the recess and is relatively high. The mixed rice is lifted up to a certain position and then falls down, and the paddy of the mixed rice falls from a position lower than the brown rice.Using this movement, the brown rice falling from a higher position is received by the brown rice receiving trough and taken out. In this case, the height at which brown rice and paddy fall is inversely proportional to the amount of mixed rice supplied into the sorting barrel, that is, the thickness of the fluidized bed of mixed rice in the sorting barrel. , tends to be lower than for a given fluidized bed thickness, and as the fluidized bed becomes thinner, it tends to be higher than for a given fluidized bed thickness. Therefore, if the height of the side plate on the left and right sides of the brown rice receiving trough on the side that scrapes up the mixed rice in the sorting cylinder is constant, that is, unchanged, when the thickness of the fluidized bed in the sorting cylinder becomes thicker. In this case, the amount of brown rice entering the brown rice receiving trough is small (as a result, the sorting efficiency decreases). Since the amount of paddy decreases, the sorting accuracy will decrease.

Therefore, Japanese Utility Model Application Publication No. 56-172383 as a prior art discloses that, among the left and right side plates of the brown rice receiving trough, the upper end of the side plate on the side for raking up mixed rice in the sorting cylinder is provided with a structure that is rotatable in the rotational direction of the sorting cylinder. It is proposed to provide an adjustment plate configured as follows.

[Problems to be Solved by the Invention] The present invention solves the problems that occur when a plurality of rotary sorting devices are arranged in parallel as disclosed in the prior art.

That is, in the rotary sorting device disclosed in the prior art, the adjusting plate in the sorting barrel is manually rotated according to the amount of mixed rice in the sorting barrel, that is, the thickness of the fluidized bed. Therefore, if multiple rotary sorting devices are installed in parallel to increase the sorting capacity and mixed rice from the huller is distributed to each device, the amount of rice in each sorting barrel will be reduced. The adjustment plates must be adjusted separately, in other words, there are many adjustment points, and each must be adjusted manually, making the adjustment extremely difficult and requiring considerable skill. It requires.

[Means for solving problems]

Therefore, the present invention provides a sensor for detecting the thickness of the fluidized bed in the sorting cylinder, and by associating the sensor with an adjustment plate in the sorting cylinder, the adjustment plate adjusts the thickness of the fluidized bed in the sorting cylinder. While the operation is automated, each adjustment plate in a plurality of sorting cylinders is operated simultaneously by one sensor provided in one sorting cylinder, thereby simplifying the structure.

Therefore, in the present invention, a plurality of rotary sorting cylinders each having a plurality of concave portions formed on the inner peripheral surface are installed horizontally, and the mixed rice from the culling device is transferred to each sorting cylinder at one end of each sorting cylinder. While the means for distributing and supplying is visible, each of the sorting cylinders is provided with an open-top brown rice receiving gutter extending in the axial direction of the sorting cylinder, and the left and right side plates of the brown rice receiving gutter in each sorting cylinder are provided. Adjustment plates configured to be freely adjustable are provided at the upper ends of the side plates on the side of scraping up the mixed rice in the sorting cylinders, and in one of the plurality of sorting cylinders, a A sensor for detecting the thickness of the fluidized bed of mixed rice is provided, and the sensor and an adjustment plate in each sorting cylinder are connected so that the adjustment plate operates to adjust in accordance with the detection of the fluidized bed thickness by the sensor. This is what I did.

[Effect]

With this configuration, the mixed rice from the huller is distributed and supplied into each of the plurality of sorting cylinders, and the function of sorting brown rice from the mixed rice so that it enters the brown rice receiving trough is performed in each sorting cylinder. When the amount of mixed rice from the huller is small, the thickness of the fluidized bed of mixed rice in each sorting barrel becomes thin, and when the amount of mixed rice from the huller is large, , the thickness of the fluidized bed of mixed rice in each sorting cylinder becomes thicker.

In this case, since the sensor installed in one of the sorting cylinders is related to the adjustment plate in each of the plurality of sorting cylinders, the adjustment plate in each of the plurality of sorting cylinders is It is automatically adjusted according to the thickness of the fluidized bed of mixed rice.

[Effects of the Invention] Therefore, according to the present invention, the adjusting plate in each of the plurality of sorting cylinders can be automatically adjusted according to the thickness of the fluidized bed of mixed rice in the sorting cylinder. There is no need for the trouble of adjusting the adjustment plates in each of the sorting cylinders separately, and there is no need for a high level of skill to adjust the adjustment plates corresponding to the fluidized bed of mixed rice in the sorting cylinder.
Work efficiency can be significantly improved.

Moreover, in the present invention, the adjustment plates in all the sorting cylinders are adjusted by a sensor installed in one of the plurality of sorting cylinders, and the adjustment plates in each sorting cylinder are adjusted. It is not necessary to install a sensor in each sorting cylinder (in other words, a sensor for automatically adjusting the adjustment plates of multiple sorting cylinders only needs to be installed in one sorting cylinder). The structure is significantly simplified, and it is possible to install a fluidized bed senic acid for other purposes in a sorting cylinder that is not equipped with a sensor IJ for adjusting all the adjustment plates. It also has an effect.

In addition, the inside of both sorting cylinders 31 and 32 are arranged on the discharge side 31'', 32
On the way, the mixed rice moves toward the brown rice receiving troughs 38, 44 and the mixed rice receiving trough 42 as described above.
, 4B, the discharge side 31"
, 32'', it becomes almost only paddy, and the mixed rice on the discharge side 31'' of the first sorting barrel 31 enters the paddy supply hopper 5 in the misbehavior device 2 from the chute 67 via the merging gutter 70, while The mixed rice on the discharge side 32'' of the second sorting cylinder 32 is once lifted to the top by a plurality of raking blades 68 on its inner surface, and then the paddy receiver enters the chute 69, and this paddy receiver flows from the chute 69 to the confluence 810. By entering into the paddy supply humper 5 in the misbehavior device 2 through the misbehavior device 2, the misbehavior action is performed again in the misbehavior device 2.

Then, the amount of mixed rice supplied into both sorting cylinders 31 and 32 is larger than the predetermined amount, and the thickness of the fluidized bed M in both sorting cylinders is less than the predetermined value shown by the solid line in FIG. When the thickness increases as shown by ', the sensor plate 72 provided in the first sorting cylinder 31 rotates clockwise in the direction of arrow B as shown by the dashed line. The adjusting plates 50° and 51 of the brown rice receiving troughs 38 and 44 in 32 are rotated clockwise in the direction of the arrow as shown by the dashed line through the related mechanism 73, so that when the fluidized bed is thick, it is automatically adjusted. , the amount of mixed rice fed into the two sorting cylinders 31 and 32 is less than the predetermined amount, and the thickness of the fluidized bed M in the separate cylinder is less than the predetermined value shown by the solid line in FIG. When the thickness becomes thinner as shown by M'', the sensor plate 72 provided inside the first sorting cylinder 31 becomes thinner as shown by the two-dot chain line.
Since the sensor shaft 71 rotates counterclockwise, the brown rice receiving troughs 38 and 44 in both sorting cylinders 31 and 32
By rotating the adjustment plates 50, 51 to the left in the direction of arrow C as shown by the two-dot chain line through the related mechanism 73, the case where the fluidized bed is thin is automatically dealt with.

In addition, although the above embodiment was a case of a three-barrel type using two sorting barrels, the present invention is not limited to this three-barrel type;
Needless to say, this can be applied even when two sorting cylinders are used (Also, the relationship between the sensor plate 72 and the readjustment plates 50 and 51 is not limited to the mechanical relationship in the embodiment, but also includes electric or hydraulic related means.
